Bug ID: 110719
Summary: Crash in radeon_drv_video.so when attempting to
convert rgb video data
Product: Mesa
Version: git
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: oreaus@gmail.com
QA Contact: dri-devel@lists.freedesktop.org
Kernel 5.0.0
Mesa 19.2.0-devel (git-629806b55b)
OpenGL renderer string: AMD Radeon (TM) RX 460 Graphics (POLARIS11, DRM 3.27.0,
5.0.0, LLVM 8.0.0)
I can reproduce the crash with this command:
`ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i input.mp4 -vf
'format=rgb0,hwupload' -vcodec h264_vaapi -bf 0 output.mp4`
The input video does not have to be rgb0 format, this command just tells it
that it is to demonstrate the problem. av_hwframe_transfer_get_formats()
reports rgb0 is supported but clearly there's a problem. This is the backtrace
for h264_vaapi:
Thread 1 "ffmpeg" received signal SIGSEGV, Segmentation fault.

It seems the driver should support this format or at least just report only the
formats it actually supports.
Please note that this bug was discovered by a screen recorder implementing
vaapi. Passing rgb data to the intel vaapi driver works as expected.
